Application filed June 2D, 1321.

This invention relates to an improvement in sofa-bedsteads, that is, an article of furniture adapted to be used as a sofa or as a bed according to the positions of some of its parts.

An object vof this invention is to provide a sofa-bedstead which is exceedingly simple, and is of such construction that the parts which. carry the seat and the back also directly support the mattress when the sofa is converted into a bed. Thus the number of parts and the cost and time of manufacture are reduced to a minimum, the addition f and mounting of extra members or attach- 'i ments to permit the `adjustments required is avoided; no complicated structure is obtained; and at the same time a very neat, flnished and comfortable sofa or bed, which can be made as ornamental or attractive as one may wish, is produced, and all the manipulation necessary to produce the desired result can be easily and quickly effected.

Other objects and advantages of this invention will appear from the following description taken with the accompanying drawings, which show the best form of the invention now known to me; and the characteristics ofmy invention are defined in the appended claim. This disclosure however, is explanatory only and l may change the construction actually shown herein, particularly as to shape, size and arrangement of parts, without departing from the nature of the invention, to the full extent indicated by the broad and general meanings ofthe terms in which the claim arek expressed.

On the drawings:

Figure l6 is a top view of the entire structure extended to make a bed, the spring mat-- tress Vbeing included and Figure 7 is a view of a detail.

The same numerals identify the Y same parts throughout.

In the detailed description of the sofabedstead illustrated in the drawings, I use the numeralv l to indicate -the framework which supports the various parts, while 2 indicates a cushion normally disposed in the lower part v'of `.the framework to serve asa seat, and 3 indicates a similar cushion, normally extending upward from the rear edge of the cushion 2 to provide a back. llVhen the seat 2 and back 3 occupy the relativepositions shown in Figures 1,2 and 3 for example, the entire construction can be used as a sofa; but whenl the yparts which support the seat 2 and back 3 are extended as indicated in Figures 5 and 6, the construction is in readiness to serve for a bed. The parts of the sofa-bedstead which carry the seat 2 and back 3 will then be in line with each other with the faces of the cushions turned downward towards the floor, and the said parts will then support an extended spring mattress 4:, (see Figure 6), on which cushions or a mattress of felt, bedding, etc., can be spread to make a comfortable resting place. When the parts carrying the seat 2 and back 3 are folded together to hold the seat and back in the positions they should occupy when the structure is'used as a sofa, the mattress 4 is folded inside of the sofabedstead as illustrated in Figure 7, and rendered entirely invisible, in a manner that will be hereinafter fully set forth.

The framework l comprises a pair of front legs united by a cross piece or bar 6, and a pair of rear legs 7 united by a cross piece 8. The legs 5 and7 and the cross-piece 6 may be of wood, whilethe rear cross piece S may be of angle iron; and angle bars v9 may run from the beam 6 adjacent the front legs 5 vto the rear `legs 7 atreach side of the sofabedstead to lj .oin' the ends of the'cross beams` 6 and 81 together. Side arms-l0 arealso present, extendingfrom lthe. rear .legs 7 to thetops of the `frentlegs I5 andthe spaces between the-.legs y5l 7 thearms l0 and the ,angle-bars 9ateachi or lside ofi-the 'sofa-hedstead -may Vfilled inby- .continuous Panels-Slt shisha-nay- :bs-f dell, niodfaer iii upholsterj,7 as desired` The rear legs 7 are ot' greater length or height than the front legs 5 and are joined at their' upper ends by a top 12. A back 13 may be provided to join the legs 7 at the rear. This back extends `from the cross piece 8 up to and above the rear ends of the arms 10 and the upper edge of this back may be in proximitj7 to or may' abut the lower edge. of a folding panel 11; which, not onljY assists in hiding' from view one end of the mattress 4e under the bach 3 when the seat 2 and back 3 are disposed in position to give the apparatus the form of a soia, but also serves as a foot board when the apparatus is extended to be used as a bed, as is hereinafter more fully described.

To 'the trout ends ot the angrle bars or beams 9 are secured a pair oi angle beams 15 by hinfres 16. The angle beams 9 are iixedlj' mounted with one web of each beam vertical and extending;` downward and the other web horizontal.: and the horizonta webs ot' these beams extend towards each other. In similar position are the angle beams 15, which are shown as having' their horizontal webs attached to the horizontal webs of the beams 9 so that the beams 15. can be 'wung back towards the legs 7 to enable them to be rolded down upon the tops of the beams 9 or in the opposite direction to bring' them into line with the beams 9, the horizontal and vertical webs oil? thV beams 9 and 15 then abutting'. Further to the ends or" the beams 15 remote from the beams 9 are ai'xed angle beams 17 by pivot pins 18, uniting the vertical webs, the joint being' made in such a manner that the horizontal webs of the angle beams 1T will abut the horizontal webs of the beams 15 when the parts are in the positions snown in Figures 5 and (l. The ends of the horizontal webs of these beznns 1T, by abutting against the ends et the horizontal webs of the angle beams 15, limit the movement'. oi" the angle beams 1T so that when the beams 1T are moved into line with the beams 15 they cannot move any further. l may emplojv springs 19 on each side to unite beams 9 to the beams 15 below the hinges and similar springs 19 attached to the beams 15 and the beams 1T below the axis of the pins 1S; so that when the soia is extended the springs will act to l-Leep the beams 9, 15 and 17 in alinement. The springs 19 adjacent the pins 1S are iixed to the vertical webs ot the beams 15 and 1i', inside, below the horizontal webs; and the springs 19 at the hinges 16 may be joined to the outside of the vertical webs of the beams 9 and 15; or, as shown in Figure 6, to the inside of the vertical ribs, but in this case projecting anchor-.pins 2O must be aihxed to the vertical webs to enable the said springs to clear the horizontal webs and pre vent the springs from interferingWitlrthe folding' down of the beams 15 on the beams 9. rEhe mattress, of course, extends, all the wajv from the cross piece 8 to the ends of the beams 1T and the horizontal webs of the beams 9, 15 and 1T will be perforated to enable the mattress to be held in place. lVhen the seat Q and back 3 are folded into the Ytrameworh 1, to convert the apparatus into a seta, the mattress will be folded in the .same manner as the beams 15 and 17, as indicated in Figure 7, and be completely covered and rendered inv'sible. rl'he outer ends oi" the. beams 17 will be joined by a cross piece 21 and to this cross piece the loldiug' panel 1l will be secured by suitable hinges. r he outer end or foot of the mattress 1 may be attached to the cross piece 21 in anj.Y convenient way.

The numeral indicates legs on the angle beams 15 adjacent the hinges 18 which join tiem to the beams 17, and similar' legs 23 are attached to the sides ot the beams 1T adjacent the end cross piece 21. The legs 22 are iis; d, while the legs 23 are pivoied. I prefer to malte the legs of the shape ot an l., inverted when the beams 9, 15 and 1T are in line, as in Figures 5 and the horizontal limbs joined to the outside of the vertical webs oiE the beams 15 and tne vertical limbs overlapping the adjacent ends of the beams 17. The ends of the panel 1li joined to links 2l, pivoted to the corners f the legs Q2 adjacent the hinges 1S, so `iat when the beams 15 are swung' into line ith the beams 17, the legs 23 vill be moved o support the outer ends ot' the beams 1T, .nd the links Qliwill act to turn up the panel 1- into the position of' a foot board. The eg's Q3 each have a lateral projection 25 by 'hich the)Y are pivoted to the vertical sides i' the beams 17 and the upper ends ot' these .ogs are joined by links QG to the pivots ol he links Q1 pinning' them to the panel 141-. When the )cams 15 and 17 are moved into line 'ith each other and with the beams 9, the action or" the links 21 in swino'ing the panel 14 into the position of a 'foot board causes the linlis 2G to pull on the upper ends of the legs 23 in such a manner as to swingr the legs outward and to malte then project at right angles to the beams 1T. lVhen the cushions are placed on the mattress and some one lies down on the bed, the bars 15 and 17 rest. accordinglyY on the legs and 523 and the parts of the soa-bedstead are supported as firmly as they should be.

Of course the seat Q and back 3 can be made in anjv desired st vle and can be mounted on panels or trames 27 which will be made fast to the edges of the vertical webs of the angle beams 15 and 17. These cushions are indicated in broken lines in Figure #1, and in full lines on Figure e.

En practice when the apparatus 1s to be used as a sofa the' beams 15 are turned s0 as to be folded down upon the beams 9, the seat 2 being thus disposed in horizontal position between the arms 10; while the beams 17 are turned up at the back, holding the cushion 3 in place at the rear edge of the seat. At this time, the beams 17 and cross piece 21 will liev in the space enclosed by the upper part of the legs 7 and the top; and thus the legs 23 and the links 24 and 26 will be snugly arranged in folded positions, between the upper parts of the legs 7 and the sides of the beams 17, and these legs and beams may be of such dimensions as to cover these legs and links completely. Even if these legs and links are not entirely covered, they will not project far enough to make ones back uncomfortable because of the presence of the cushion rl"hese legs land links will then be wholly or partly hidden from view by the legs 7 except along their edges; which can be seen between the legs 7 and the beams 17 while the legs 22 may project upward along the inner faces of the sides 11 and the arms 10 adjacent the rear legs 7. The legs 22 can be made of metal and they will be out of the way entirely and not likely to interfere with any one seated on the seat 2. The spring mattress l under these conditions will entend from the cr ss piece 8 along the beams 9 to the hinges 16, then back to the pins 18 and up to the cross piece 21, (see Figure 7), thus being entirely enclosed and hidden from view but in such position that nothing more than the swinging forward of the bac-k 3 with the beams 17 and the lifting of the seat 2 with the beams 15 are required to enable the beams 15 and 17 to be turned out in front and lowered and the legs 22 and 23 to rest upon the floor, in order to make the apparatus ready as a bed. This movement of the parts, of course distends the mattress et and the action of the links 9A pulls on the links 25 and swings the legs 28 iuto position. To convert the bed into a. sofa the parts are merely moved backward in the same way. y

lf desired, cross pieces 28 may be used to unite the ends of the beams 9 and beams 15 adjacent the hinges 16, to close the front of the sofa bedstead below the seat 2. These pieces 28 may have opposed recesses as at 29,

to avoid interfering with the springs 19 adjacent the hinges 16.

The sofa-bedstead will thusbe seen to be made up of the smallest possible number of parts; and when used as a. sofa it presents a very neat and finished appearance, the same as an ordinary sofa. When it is used as a bed, the same parts which ordinarily support the seat and back will directly support the mattress, and the cushions which are laid down on it. No cumbersome or complicated attachments are therefore used, and the apparatus can not only be manufactured at a low cost and at a. minimum of time and labor, but it also is very easy to manipulate, to enable it to be used either as a sofa or a bed as the occasion demands.

As will be understood the sofa-bedstead will be given various ornamental forms' and can be made in various sizes and with its dimensions varied to suit. The drawings show it wider in front than at the back, with the seat 2, supported on the beams 15, of such shape as to lit snugly between the sides 11, but obviously the same width may be given to both back and front whenever desired.

Having described my invention, what I believe to be new and desire to secure and protect by Letters Patent of the United States, is :e

A sofa-bedstead comprising a framework, parts for carrying a seat having hinged connection with the front of the framework, parts for carrying a back having hinged connection with the parts for carrying a seat, the parts for carrying the back and the parts vfor carrying the seat being movable into line with each other, springs con# nected to the parts for carrying the seat and the parts for carrying the back, and crosspieces attached to the front of the framework and the parts for carrying the seat adjacent the front of the said framework, said crosspieces having opposed recesses to register and receive said springs, when the parts are extended, as set forth.

In witness whereof, l have signed my name to this specification, the 2nd day of' May, 192i.
